Public health response to large influx of asylum seekers: implementation and timing of infectious disease screening

Use of healthcare services preceding HIV diagnosis - missed opportunities for earlier diagnosis, Finland, 1996 to 2019

BackgroundHIV testing based on indicator conditions is recommended to diagnose HIV earlier.AimOur aim was to assess opportunities for earlier diagnosis of HIV.MethodThis is a retrospective study on people living with HIV (PLWH) included in the national HIV register. We collected data on public primary outpatient healthcare (PHC) (2011-2019), secondary and tertiary outpatient healthcare (STHC), and all inpatient care (1996-2019) from the Care Register for Health Care from the presumed acquisition, estimated by CD4+ T-cell count at diagnosis, until the diagnosis of HIV.ResultsOf 907 PLWH diagnosed between 2011 and 2019, 522 (58%) had ≥ 1 healthcare contact at any level between HIV acquisition and > 30 days before diagnosis. At least one European Centre for Disease Prevention and Control (ECDC) indicator condition was recorded for 119 (23% of 522), and 112 (21%) were born in a high-prevalence country. In total, 384 of 907 (42%) had visited a PHC physician, and 58% of those with CD4+ T-cell count < 200 cells/μL at diagnosis. Of 2,082 PLWH diagnosed between 1996 and 2019, 869 (42%) had STHC outpatient contacts > 30 days before diagnosis, 18% with ≥ 1 ECDC indicator condition, and 367 (18%) had been hospitalised, 20% with ≥ 1 ECDC indicator condition. The most common ECDC indicator conditions > 30 days before diagnosis at all levels of healthcare were pneumonia, sexually transmitted infections, unexplained fever, herpes zoster, pregnancy and lymphadenopathy.ConclusionWe recommend enhancing indicator condition-based HIV testing by all healthcare providers, particularly for gonorrhoea, syphilis and, for persons younger than 50 years, also herpes zoster and lymphadenopathy.

Systematic review exploring the burden of sexually transmissible infections and bloodborne viruses in refugees and asylum seekers: insights to inform policy and practice

BACKGROUND

In 2022, the number of refugees and asylum seekers (RAS) have reached an all-time high of 40.7 million globally. The surge in RAS, coupled with their limited access to healthcare (at their home and destination countries), has led to the risk of transmitting/acquiring sexually transmissible infections (STIs) and bloodborne viruses (BBVs). This situation threatens the health of RAS and poses a public health challenge to destination countries, potentially placing a burden on healthcare systems and resources. Healthcare recommendations for screening programmes for RAS vary between countries, leading to disparities in STI/BBV screening practices on arrival. These disparities can impact early detection and treatment of STIs/BBVs, increasing the risk of onward transmission and long-term negative sequelae. Therefore, this systematic review aims to investigate the prevalence and factors associated with STIs/BBVs among RAS.

METHODS

Six databases (ie, PubMed, Embase, Scopus, Cochrane Library, Web of Science and CINAHL) were searched for observational studies reporting STIs/BBVs prevalence and/or risk factors among RAS. The inverse variance heterogeneity model with double arcsine transformation was applied to prevalence meta-analysis of STIs/BBVs by region of origin of RAS. Narrative data synthesis was undertaken to summarise risk factors associated with STIs/BBVs.

RESULTS

A total of 21 studies (n=504 432 RAS) were included. Most studies were conducted among RAS arriving in Europe (n=14), followed by North America (n=5) and Australia (n=2). The highest prevalence of HIV (1.55%; 95% CI 0.53 to 3.04), syphilis (1.29%; 95% CI 0.59 to 2.24) and hepatitis B (6.50%; 95% CI 2.29 to 12.46) were observed among RAS from sub-Saharan Africa. The highest prevalence of hepatitis C was found in RAS from Southeast Asia (3.96%; 95% CI 2.74 to 5.38) and North Africa (3.59%; 95% CI 1.33 to 6.79). The highest prevalence of chlamydia was reported among RAS from the Middle East (1.48%; 95% CI 0.00 to 4.73) and Eastern Europe (1.40%; 95% CI 0.38 to 4.96). History of STIs, torture, blood transfusion and African origin were identified as factors associated with increased prevalence of STIs/BBVs.

CONCLUSIONS

This study underscores the regional disparities in the burden of STIs/BBVs among RAS. These findings highlight the importance of targeted screening for STIs/BBVs based on the country/region of origin and individual risk factors, and implementation of mitigation measures (eg, improving healthcare access and raising awareness) tailored to their unique needs. Such measures are crucial for reducing the impact of STIs/BBVs in both RAS and host countries.

Hepatitis B infection and immunity in migrant children and pregnant persons in Europe: a systematic review and meta-analysis

BACKGROUND

The WHO's global hepatitis strategy aims to achieve viral hepatitis elimination by 2030. Migrant children and pregnant persons represent an important target group for prevention strategies. However, evidence on the burden of chronic hepatitis B (CHB) infection and the factors affecting its incidence is lacking.

METHODS

EMBASE, Global Health, Global Index Medicus, Web of Science and Medline were searched for articles in any language from 1 January 2012 to 8 June 2022. Studies reporting CHB prevalence, disease severity, complications and/or prevention strategies, including vaccination, prevention of vertical transmission and access to care/treatment for migrant children and pregnant migrants, were included. Pooled estimates of CHB prevalence and hepatitis B vaccination (HBV) coverage among migrant children were calculated using random effects meta-analysis.

FINDINGS

42 studies were included, 27 relating to migrant children and 15 to pregnant migrants across 12 European countries, involving data from 64 773 migrants. Migrants had a higher incidence of CHB than host populations. Among children, the pooled prevalence of CHB was higher for unaccompanied minors (UAM) (5%, [95% CI: 3-7%]) compared to other child migrants, including internationally adopted children (IAC) and refugees (1%, [95% CI: 1-2%]). Region of origin was identified as a risk factor for CHB, with children from Africa and pregnant migrants from Africa, Eastern Europe and China at the highest risk. Pooled estimates of HBV vaccine coverage were lower among UAM (12%, [95% CI: 3-21%]) compared to other child migrants (50%, [95% CI: 37-63%]).

CONCLUSION

A range of modifiable determinants of HBV prevalence in migrant children and pregnant persons were identified, including sub-optimal screening, prevention and continuum of care. There is a need to develop evidence-based approaches in hepatitis care for these groups, thereby contributing towards global viral hepatitis elimination goals.

The impact of population influx on infectious diseases - from the mediating effect of polluted air transmission

The global population influx during the COVID-19 pandemic poses significant challenges to public health, making the prevention and control of infectious diseases a pressing concern. This paper aims to examine the impact of population influx on the spread of infectious diseases, with a specific emphasis on the mediating role of air pollution in this process. A theoretical analysis is conducted to explore the relationship between population influx, air pollution, and infectious diseases. Additionally, we establish a series of econometric models and employ various empirical tests and analytical techniques, including mediation effect test, threshold effect test, and systematic GMM test, to evaluate our hypotheses. The results indicate that: (1) Population influx directly and indirectly impacts infectious diseases. Specifically, population influx not only directly elevates the risk of infectious diseases, but also indirectly increases the incidence rate of infectious diseases by intensifying air pollution. (2) The impact of population inflow on infectious diseases exhibits regional heterogeneity. Compared to central and western China, the eastern regions exhibit a significantly higher risk of infectious diseases, exceeding the national average. (3) External factors influence the relationship between population influx and infectious diseases differently. Personal income and medical resources both help mitigate the risk of infectious diseases due to population influx, with medical resources having a more substantial effect. Contrary to expectations, abundant educational resources have not reduced the risk, instead, they have exacerbated the risk associated with population influx. This paper provides a scientific basis for formulating effective strategies for the prevention and control of infectious diseases.

Prevention, testing, and treatment interventions for hepatitis B and C in refugee populations: results of a scoping review

BACKGROUND AND AIMS

Refugees are at higher risk for hepatitis B (HBV) and hepatitis C (HCV), but often face unique healthcare barriers to vaccination, testing, and treatment. This scoping review aimed to identify and characterize HBV and HCV prevention and care services serving refugee populations globally.

METHODS

A literature search was conducted on Embase, Cochrane, and PubMed databases. Research studies published in English between January 2010 to July 2022 describing an HBV or HCV prevention, testing, or treatment intervention for refugees were included.

RESULTS

There were a total of 69 articles reporting viral hepatitis prevalence, implementation of services, or economic modelling. Of the 38 implementation studies, 14 were stand-alone HBV and/or HCV interventions, while 24 studies included HBV and/or HCV in an intervention targeting multiple infectious diseases and/or parasitic infections. Interventions commonly included a testing (n = 30) or referral (n = 24) component. Frequently reported features to promote program accessibility included bilingual services (n = 25), community partnerships (n = 21), and multidisciplinary staff members (n = 18), such as cultural and/or linguistic mediators, community health workers, community health leaders, lay health workers, local health staff, members of the refugee community, and social workers. The most commonly reported challenge was the transience of refugees (n = 5). Twenty studies noted funding sources, of which twelve reported governmental funding (not including national health insurance) and eight reported that refugees received national health insurance.

CONCLUSIONS

This is the first scoping review to characterize the types of hepatitis prevention, screening, and treatment interventions serving refugee populations globally. Published experiences of HBV and HCV services for refugee populations remain limited. Additional efforts are needed to disseminate models of hepatitis interventions for refugees to ensure access to care for this key population. To achieve hepatitis elimination globally, best practices must be identified and shared to expand access to hepatitis services for refugee populations.

A scoping review of sexual and reproductive health recommendations in the context of migration to Europe

In recent years, growing instability and conflict around the world have continued to fuel outward migration, including migration to the EU/EEA. Many migrants hail from countries and regions with a higher burden of STIs-including HIV-and are exposed to enhanced risks of sexual and gender-based violence leading to sexual health issues during their journeys. This scoping review aims to identify existing sexual health recommendations for non-European migrants in the EU/EEA and identify gaps in their implementation. Sexual health recommendations formulated in relation to the migrant population in peer- reviewed journals or by expert consensus, between 2010 and 2021, were included. A keyword search was used to retrieve relevant publications on PubMed, ScienceDirect, the Cochrane Library databases, WHO and ECDC websites. The search strategy employed was charted in a dedicated Prisma Chart. Overall, 180 publications were retrieved. Based on the abstract and after eliminating duplicates, 33 publications were included for full-text reading. The references of these publications were screened. In total, 19 publications met the inclusion criteria. Evidence-based sexual health recommendations target only newly arrived migrants and migrant children (at arrival and during stay in the country). Screening practices are mostly informed by the country of origin and related prevalence, which remains a limitation; challenges faced during migration should also be considered. Implementation and compliance with these recommendations remain uncertain, as sexual health is not funded and addressed in a uniform manner across Europe.

Estimates of hepatitis B virus prevalence among general population and key risk groups in EU/EEA/UK countries: a systematic review

BackgroundThe burden of chronic hepatitis B virus (HBV) varies across the European Union (EU) and European Economic Area (EEA).AimWe aimed to update the 2017 HBV prevalence estimates in EU/EEA countries and the United Kingdom for 2018 to 2021.MethodsWe undertook a systematic review, adding to HBV prevalence estimates from an existing (2005-2017) database. Databases were searched for original English-language research articles including HBV surface antigen prevalence estimates among the general population, pregnant women, first-time blood donors (FTB), men who have sex with men (MSM), migrants and people in prison. Country experts contributed grey literature data. Risk of bias was assessed using a quality assessment framework.FindingsThe update provided 147 new prevalence estimates across the region (updated total n = 579). Median HBV prevalence in the general population was 0.5% and the highest was 3.8% (Greece). Among FTB, the highest prevalence was 0.8% (Lithuania). Estimates among pregnant women were highest in Romania and Italy (5.1%). Among migrants, the highest estimate was 31.7% (Spain). Relative to 2017 estimates, median prevalence among pregnant women decreased by 0.5% (to 0.3%) and increased by 0.9% (to 5.8%) among migrants. Among MSM, the highest estimate was 3.4% (Croatia). Prevalence among people in prison was highest in Greece (8.3%) and the median prevalence increased by 0.6% (to 2.1%).ConclusionsThe HBV prevalence is low in the general population and confined to risk populations in most European countries with some exceptions. Screening and treatment should be targeted to people in prison and migrants.

A systematic review of barriers and facilitators for hepatitis B and C screening among migrants in the EU/EEA region

Introduction

Hepatitis B and C are a threat to public health. Screening of high-risk groups, such as migrants from high-endemic areas, enables early identification and treatment initiation. This systematic review identified barriers and facilitators for hepatitis B and C screening among migrants in the European Union/European Economic Area (EU/EEA).

Methods

Following PRISMA guidelines, databases PubMed, Embase via Ovid, and Cochrane were searched for English articles published between 1 July 2015 and 24 February 2022. Articles were included, not restricted to a specific study design, if they elaborated on HBV or HCV screening in migrant populations from countries outside Western Europe, North America, and Oceania, and residing in EU/EEA countries. Excluded were studies with solely an epidemiological or microbiological focus, including only general populations or non-migrant subgroups, or conducted outside the EU/EEA, without qualitative, quantitative, or mixed methods. Data appraisal, extraction, and quality assessment were conducted and assessed by two reviewers. Barriers and facilitators were categorized into seven levels based on multiple theoretical frameworks and included factors related to guidelines, the individual health professional, the migrant and community, interaction, the organization and economics, the political and legal level, and innovations.

Results

The search strategy yielded 2,115 unique articles of which 68 were included. Major identified barriers and facilitators to the success of screening related to the migrant (knowledge and awareness) and community level (culture, religion, support) and the organizational and economic level (capacity, resources, coordinated structures). Given possible language barriers, language support and migrant sensitivity are indispensable for facilitating interaction. Rapid point-of-care-testing is a promising strategy to lower screening barriers.

Discussion

The inclusion of multiple study designs provided extensive insight into barriers, strategies to lower these barriers, and facilitators to maximize the success of screening. A great variety of factors were revealed on multiple levels, therefore there is no one-size-fits-all approach for screening, and initiatives should be adopted for the targeted group(s), including tailoring to cultural and religious beliefs. We provide a checklist of facilitators and barriers to inform adapted interventions to allow for optimal screening impact.

Comparison of syphilis seropositivity between non-immigrant and immigrant populations in the Anatolian side of Istanbul, Turkiye: Results of five-years retrospective study

OBJECTIVE

Our study aimed to evaluate the seropositivity for syphilis in non- immigrant and immigrant populations and compare the results regarding demographic data.

METHODS

In accordance with the reverse algorithm, syphilis tests were performed between May 2014 and December 2018 in hospitals in our service zone for syphilis screening or symptomatic disease.

RESULTS

A total of 135.328 non- immigrant and 6.641 immigrant were screened for syphilis. Seropositivity rates were 1.3% in the non- immigrant and 3.8% in immigrant groups (p=0.0001). There was a statistically significant difference in terms of seropositivity rates between the various age groups in the local group and immigrant groups (except 18 25 age group) (p<0.05). Syphilis seropositivity rates were found to be lower in indigenous population than immigrant groups according to the years tested (p=0.0001). The seropositivity rates were 2.4% and 3.2% among the males (p=0.025) and 0.6% and 4.0% among females (p=0.0001) in non-immigrantand immigrant groups, respectively. Whereas, 0.6% of pregnant women in the local group and 3.7% of pregnant women in immigrant groups were seropositive for syphilis (p=0.0001). Among the HIV positive group, syphilis seropositivity was only observed in the non-immigrant group with a rate of 23.0% (p=0.0001).

CONCLUSION

The antibodies against syphilis were found more frequently in immigrants than non-immigrant. Among the HIV positive individuals syphilis seropositivity was only observed in the non-immigrant group.

Health status and healthcare trajectory of vulnerable asylum seekers hosted in a French Reception Center

BACKGROUND

Europe lacks studies related to asylum-seekers' health.

METHODS

We described the health status, healthcare and follow-up of men seeking asylum, accommodated in a primary reception center in Paris (CPA). This observational study included volunteer patients presenting for care at the CPA primary care unit (PCU) from January to March 2018. They could be referred to on-site GPs and psychiatrists or to surrounding healthcare facilities. After their asylum application, patients were transferred to other French accommodation centers. PCU healthcare professionals could make referrals for close medical reassessments after transfer.

RESULTS

The 728 included men came mostly from Central Asia or Middle East (65%) and Africa (34%). Seventy percent reported violence during migration. Seventy-five percent (547/728) were referred to on-site GPs, 20% to psychiatrists. During patients' stay at CPA, 67% (144/214) of referrals to surrounding healthcare facilities led to performed consultations. Seven percent of all the included patients (49/728) were referred for frequent communicable infectious diseases screening. Final diagnoses (n = 1108) included 31% infectious diseases and 7% psychiatric disorders. When post-transfer accommodation centers could be reached, 69% (33/48) of the medical referrals had led to a scheduled appointment.

CONCLUSIONS

The healthcare trajectory at CPA could benefit from optimization of infectious and psychiatric screenings, and improved coordination of care and follow-up.

Paediatric tuberculosis during universal and selective Bacillus Calmette-Guérin vaccination policy: a nationwide population-based retrospective study, Finland, 1995-2015

Introduction

In 2006, the Bacillus Calmette–Guérin (BCG) vaccination policy in Finland changed from universal to selective.

Aim

We assessed the impact of the policy change on tuberculosis (TB) morbidity in children under 5 years and epidemiological trends of paediatric TB in Finland.

Methods

We conducted a nationwide, population-based, retrospective registry study of all newly diagnosed active TB cases younger than 15 years in Finland from 1995 to 2015 by linking data from the National Infectious Diseases Register, Finnish Care Register for Health Care, medical patient records and Finnish Population Information System. We compared the TB incidence rate ratio of under 5 year-olds with universal and selective BCG vaccinations with a Poisson log-linear model and analysed incidence trends among those younger than 15 years with a negative binomial model.

Results

We identified 139 paediatric TB cases: 50 native (including 24 second-generation migrants) and 89 foreign-born children. The TB rate of under 5 year-olds remained stable after changing to selective BCG vaccination (incidence rate ratio (IRR): 1.3; 95% confidence interval (CI): 0.7–2.3). TB rate in the native population under 15 years increased slightly (IRR = 1.06; 95% CI: 1.01–1.11).

Discussion

Paediatric TB cases in Finland were concentrated in families with migrant background from high-TB incidence countries. The native TB morbidity in under 5-year-olds did not increase after the BCG policy revision, suggesting that selective vaccinations can prevent TB in the most vulnerable age group in low-incidence settings. Second-generation migrants under 15 years in Finland with high TB risk are probably increasing.

Maternal health care utilization and the obstetric outcomes of undocumented women in Finland - a retrospective register-based study

Background

Undocumented pregnant women constitute a vulnerable group of people who lack equal access to pregnancy care. Previous research has shown that undocumented migrants encounter difficulties in accessing health services, the onset of prenatal care is delayed, and women have an increased risk for infectious diseases. The aim of this study was to describe the use of maternal health care services and the obstetric outcomes of undocumented women in Helsinki, capital city of Finland, in addition to comparing the results with all pregnant women in Finland.

Methods

The study was a retrospective register-based study consisting of data collected between 2014 to 2018 from the electronic medical records of the public maternity clinic and maternity hospital in Helsinki, Finland. The study population consists of 62 individual pregnancies of undocumented women. The results of the study were compared with national data on parturients and deliveries (N = 47,274 women) and with prenatal screening tests for infectious diseases (N = 51,447 [HIV, HBV], N = 51,446 [syphilis]).

Results

The majority (91%) of the undocumented women attended public prenatal care. However, four women received no prenatal care and three women were denied access to care. Undocumented women entered prenatal care later and had fewer visits compared with all pregnant women. The majority (71%) of the undocumented women received inadequate prenatal care as the number of visits was less than eight. Of the study population, 5% (3/59) tested positive for HIV, 3% (2/59) for HBV, and 2% (1/57) for syphilis. The prevalence of HIV (p-value < 0.001) and HBV (p-value = 0.007) was significantly higher amongst undocumented women compared with all pregnant women.

Conclusions

Undocumented women entered prenatal care later than recommended. Most women received inadequate prenatal care and some of them did not receive prenatal care at all. The prevalence of infectious diseases was significantly higher and the coverage of prenatal screenings deficient amongst undocumented pregnant women.

Delivering multi-disease screening to migrants for latent TB and blood-borne viruses in an emergency department setting: A feasibility study

BACKGROUND

Screening for latent tuberculosis infection (LTBI) in migrants is important for elimination of tuberculosis in low-incidence countries, alongside the need to detect blood-borne infections to align with new guidelines on migrant screening for multiple infections in European countries. However, feasibility needs to be better understood.

METHODS

We did a feasibility study to test an innovative screening model offering combined testing for LTBI (QuantiFERON), HIV, hepatitis B/C in a UK emergency department, with two year follow-up.

RESULTS

96 economic migrants, asylum seekers and refugees from 43 countries were screened (46 [47.9%] women; mean age 35.2 years [SD 11.7; range 18-73]; mean time in the UK 4.8 years [SD 3.2; range 0-10]). 14 migrants (14.6%) tested positive for LTBI alongside HIV [1], hepatitis B [2], and hepatitis C [1] Of migrants with LTBI, 5 (35.7%) were successfully engaged in treatment. 74 (77.1%) migrants reported no previous screening since migrating to the UK.

CONCLUSION

Multi-disease screening in this setting is feasible and merits being further tested in larger-scale studies. However, greater emphasis must be placed on ensuring successful treatment outcomes. We identified major gaps in current screening provision; most migrants had been offered no prior screening despite several years since migration, which holds relevance to policy and practice in the UK and other European countries.

Tuberculosis screening of asylum seekers in Finland, 2015-2016

Background

In Finland, asylum seekers from countries with high tuberculosis (TB) incidence (> 50/100,000 population/year) and those coming from a refugee camp or conflict area are eligible for TB screening. The aim of this study was to characterise the TB cases diagnosed during screening and estimate the yield of TB screening at the reception centres among asylum seekers, who arrived in Finland during 2015–2016.

Methods

Voluntary screening conducted at reception centres included an interview and a chest X-ray. Data on TB screening and health status of asylum seekers was obtained from the reception centres’ national health register (HRS). To identify confirmed TB cases, the National Infectious Disease Register (NIDR) data of foreign-born cases during 2015–2016 were linked with HRS data. TB screening yield was defined as the percentage of TB cases identified among screened asylum seekers, stratified by country of origin.

Results

During 2015–2016, a total of 38,134 asylum applications were received (57% were from Iraq, 16% from Afghanistan and 6% from Somalia) and 25,048 chest x-rays were performed. A total of 96 TB cases were reported to the NIDR among asylum seekers in 2015–2016; 94 (98%) of them had been screened. Screening identified 48 (50%) cases: 83% were male, 56% aged 18–34 years, 42% from Somalia, 27% from Afghanistan and 13% from Iraq. Furthermore, 92% had pulmonary TB, 61% were culture-confirmed and 44% asymptomatic. TB screening yield was 0.19% (48/25048) (95%CI, 0.14–0.25%) and it varied between 0 and 0.83% stratified by country of origin. Number needed to screen was 522.

Conclusions

TB screening yield was higher as compared with data reported from other European countries conducting active screening among asylum seekers. Half of the TB cases among asylum seekers were first suspected in screening; 44% were asymptomatic. TB yield varied widely between asylum seekers from different geographic areas.

Tuberculosis screening during the 2015 European refugee crisis

Background

The purpose of our study was to describe and evaluate management, performance and results of Tuberculosis (TB)-screening among refugees and asylum seekers in a rural area in Germany in 2015.

Methods

Refugees or asylum seekers, staying in shared-accommodation are obligated to participate on screening chest X-ray (CXR) in order to screen for signs of potentially infectious pulmonary TB (German Protection against Infection Act and German Asylum Procedure Act). n = 705 individuals underwent screening chest X-ray (CXR) to detect pulmonary TB in September and October 2015 on site. One experienced radiologist interpreted and reported each CXR within 24 h after the enrollment in the screening program and results were sent to the local Public Health Department for potential further medical care. Image abnormalities suggestive for TB were defined according to established radiographic criteria such as pleural effusion, cavitation, consolidation, fibrous scarring or calcification. Only in case of TB-suggestive findings on CXR, further diagnostics were arranged (pulmonological examination, follow-up CXR, sputum culture, interferon-gamma release assay, bronchoscopy). Follow-up data was collected in collaboration with the local Public Health Department. Descriptive statistics were calculated using GraphPad Prism software.

Results

n = 637 CXR examinations (90%) did not show abnormal findings, n = 54 CXR (8%) showed incidental findings, and n = 14 CXR (2%) were suspicious for acute TB. Of these, n = 14 individuals, eight underwent further TB diagnostics. Active TB was confirmed in one individual (0.001% of the screening cohort).

Conclusions

Our cohort reflects current immigrations statistics in Europe and illustrates an overall low TB prevalence amongst individuals entering Germany in 2015. However, our findings support the improvement of diagnostic algorithms.

Asylum seekers health and wellbeing (TERTTU) survey: study protocol for a prospective total population health examination survey on the health and service needs of newly arrived asylum seekers in Finland

INTRODUCTION

Health, well-being and health service needs of asylum seekers have emerged as urgent topics following the arrival of 2.5 million asylum seekers to the European Union (EU) between 2015 and 2016. However, representative information on the health, well-being and service needs of asylum seekers is scarce. The Asylum Seekers Health and Wellbeing (TERTTU) Survey aims to: (1) gather population-based representative information; (2) identify key indicators for systematic monitoring; (3) produce the evidence base for development of systematic screening of asylum seekers' health, well-being and health service needs.

METHODS AND ANALYSIS

TERTTU Survey is a population-based prospective study with a total population sample of newly arrived asylum seekers to Finland, including adults and children. Baseline data collection is carried out in reception centres in 2018 and consists of a face-to-face interview, self-administered questionnaire and a health examination following a standardised protocol. Altogether 1000 asylum seekers will be included into the study. Baseline data will be followed up with national electronic health record data encompassing the entire asylum process and later with national register data among persons who receive residency permits.

ETHICS AND DISSEMINATION

Ethical approval has been granted by the Coordinating Ethics Committee of the Helsinki and Uusimaa Hospital District. Participation is voluntary and based on written informed consent. Results will be widely disseminated on a national and international level to inform health and welfare policy as well as development of services for asylum seekers. Results of the study will constitute the evidence base for development and implementation of the initial health assessment for asylum seekers on a national level.
